Zwmdzwn shields G', G', made of eniiable nniierial, such as galvanizediron, which lie close to the longitudinal inner surfaces ol" ille Yl'raine around the opcning.- These shieldsl ure sector shaped and extend from tlie pivotal connection of ille cover E' 'to ille sides oil.' ille frame F. Any suitable n fansinay` be used forysecnring the upper edgel of the. shields to tlle'nnder surface oil' ille Cover E' and for securing the curved onier edges of the4 shields to the side portions of the iframe F. y', for instance, indicates an angle bracket for rigidly securing the lower edges of each of the shields to the eorreepeniling lower corner of the angular frame F'. Similar Shields G2, G2` depend `from ille cover E2 and are secured te tbe side poriions of the curved 'traine F2.

Secured beneath the cover E' at solisten tially tbe longitudinal center iliereot' is a slotted plate Il' which is engaged by and guides the upper end of a bell crank lever K', any suitable connection being provided for slidingly connecting the end oil tbe bell erank lever with the slotted plaie. The bell crank lever is pivoted upon a bracket 7i' secured to ille carline a, extending transversely across the Ventilatingopening beneath illle beam D. The lower end of ille bel] crunk lever K is pivoially connected through a slot formed therein with a stud carried by a lungitiidinally reciprocating bar L'. llie ventilator corresponding to the ventilator ll' in each of the bare A', A2, A3, A* and il operated by a Similar bell erzink lever K', all of which are connected with ille same longitudinally reciprocating bar L.

Eis Down in Fig. 5, the Sheet R extentie tra: sversely entirelgf across the bar l) and depends over/tbe, ends thereof. The inner surface el? each Ventilating ropening is pref-- titl erably covered Witha lining S made of any suitable material, as, for instance, ganvanized iron.

rlhe `operation of 4my improved ventilating svstem is as follows: vWhen all of the pairs of ventilators are in the closed positions shown in yFig. 2 and the train is moving toward the left, it desirable to preferably open the ventilator cover E2 in each pair. This is accomplished by loosening the clamp nut O Which connects the link N2 with the hand lever M2, after which the hand lever is oscillated toward the right, thereby reciprocating the bar L toward the right and oscillating each of the bell crank ,levers K2, so that the cover E2 of each of thc pairs of ventilators is oscillated upwardly, as vindicated indotted lines in Fig. rhe

agree-.to which the ventilator covers 132 are opened is determined by the extent to which the operating levcrld'2 is swung to the right, and when it hasbeen swung to the extentnece'ssary to open the ventilator covers E2 i to the desired extent,'tlie clamp screw O is adjusted to clamp the lever M2 tightly to the linlr N2, thereby locking the lever in its ad justed position and holding the ventilator covers open to the desired extent, depending upon theconditions in the kitchen andthe weather conditions. When the car is moving in an opposite direction, namely, toward the right ot' Fig. Q, all of the ventilator covers E2 are rst closed by unclamping the lever M2 from the link N2 so that the lever ,may be swung toward the left to the position shown in Fig. 2, Where it may be securely retained by again clamping the same to the end of the link N2. The lever M" is then oscillated toward the left, which reciprocates the bar L2 and oscillates each of the bell crank levers K', so that the ventilator cover E in each pair of ventilators is openedto the desired extent and retained in such opened position by adjusting the clamp screvv O so as to lock t e lever M to the link N. Ey reason of the depending ilanges around the edges of the several ventilator covers, Which overlap the frames aroundthe openings, and by reason of the Waterproofl sheets R, the'ingress of water or cinders is prevented when the ventilator `covers are closed, and when they are opened the screens and side shields prevent cinders and dust from passing therethrough into the kitchen While the screens permit the necessary -ventilation.

- 'From the foregoing description it will be an improved, adapted for thehitohen of dining cars, comprising two series of ventilators, the ventilators in each i seriesrbeing connected for simultaneous operation' andv one series or the other being opened.- erfclosed according to the direction of movement of the car. lt 'will be further observed that I have invented an improved system of car ventilation which will permit the ingress of dust, .cinders, orwater, which may be conveniently operated to cont-rol the amount of ventilation, according to Weather conditions and'conditions of the car, and which may be readily adjusted toaccord with the direction of movement of the car.

While l have described more or less in detail the specific fo-rminl which I have illustrated my invention as elnbodied, yet I do notI Wish to be understood as limiting myself thereto, as I contemplate changes in form, proportion ot' parts, and substitution of equivalents, as .circumstances may re.- quire, or as may be deemed expedient.

l. ln a ventilating systenrfor cars, the combination with a longitudinal series of ventilators in the car roof, of a leverlior opening or closing each ventilator, a longitudinally reciprocating bar to which all of said levers are pivotally connected, a handlever pivotally depending from the under side of the car root", and pivotally connected to said reciprocating bar, and a link pivotally connected to said bar and adjustably connected to said hand lever, whereby said link retains said hand lever and thereby said ventilators in adjusted'position.

2. The combination With the roof ot a car having an opening therethrough, of a pair of horizontal ventilators controlling the said opening, means for pivotally supporting the inner ends of saidventilators adjacent the transverse center of said opening,a screen depending from the free end of each veni.

tilator ivithinthe opening and close to the adjacent transverse end thereof, side shields depending -from each of said ventilators within the opening close to the adjacent longitudinal sides thereof, and means for separately vertically swinging said ventilators about their hinges.

3. The combination with the roof of a car having a plurality of longitudinally ar-` ranged openings thcrethrough, of a'pair of ventilators controlling each` of said openings, means for pivotally supporting the inner edges of the 'ventilators' in cach pair adjacent the transverse center lofthe opening controlled thereby, a screen'depending from the free end of each ventilator Within thev underlying openingl and close to the adjacent transverse end thereof, side shields depending from each of said ventilators within the underlying opening close to the adjacent longitudinal sides, thereof, and means for simultaneouslyl opening or closing the correspondingventilators of theseveral pairs.

4; The combination with the roof of a car having anopening therethrough, ofa framey on the car roof aroundlsaid opening, a beam extending across the transverse center of said opening and supported at its ends upon the sible members of the surrouncling freine,

n pair of ventilators-eontrolling said opening, means for pivotally Connecting the in-` ner'ends of said ventilators to the opposite edges of said beam, depending flanges on the side and outer edgee or", eueh ot said ventilators adapted te everlap the Side and end members oil the frame 'when the ventilz'itors are closed, a waterproof coveringr extending across said beam and overlapping the adja cent portions of :said ventilators, and means for separntely swinging said ventilators about their pivotal eonneetions with said beam.

5. The combination with the roof of a. ear having" an openiiig therethrough, of a pair of ventilatorey controlling said opening, a beam extending across the transverse Center of said opening, ineane` ilor pirotally eonl.

neeting the inner edges of said ventilators to said beam, bell crank levers pivoted at their angles upon the opposite sides of a earline extending across the transverse Center of said opening and below said beam, the upper ends of said bell crank levers projeeting in opposite orreetons, means for slidingly connecting the upper ends: of said bell crank levers with the under surfaces of said ventilators, and means for independently Aoscillating the lower ends of said bell Crank levers to independently open or close said ventilators.
